Product Description


SCOTECH'S vacuum pressure impregnated dry type transformer (VPI transformer) is a new concept of dry type transformers, the transformer coils are vacuum pressure impregnated in high temperature polyester vanish under vaccum and pressure, the coils can be made of copper or aluminum, the Insulation is made of high grade nonflammable materials, the insulations class can be F, H or C class, suitable for different requiements, the finished coils are effectively protected against moisture, dirt, and most industrial contaminants, VPI transformers are suitable for use indoor or outdoors, any place require particular attention to the environments, such as costal and mining area, it can equpped with cooling fans and temperature controller to allow it have overload capacity. it's maintenance free to save your valuable time and compact in size to save your limited space.


Suitable for almost all environmental conditions.

Low temperature rise, maximum C class insulation material suitable for high ambient temperature condition.

Compact in size

Maintenance free

Reliable quality
